B4J Question TCP Server

[Declan]

I am using the following example: https://www.b4x.com/android/forum/threads/b4x-network-asyncstreams-b4xserializator.72149/#content
I am sending data to the B4J app from a remote device.
I do not require any "Prefix" or "Header" in the message and have changed to:

Private Sub ListenForConnections
    Do While working
        server.Listen
        Wait For Server_NewConnection (Successful As Boolean, NewSocket As Socket)
        If Successful Then
            CloseExistingConnection
            client = NewSocket
            astream.Initialize(client.InputStream,  client.OutputStream, "astream")
            UpdateState(True)
        End If
    Loop
End Sub

This throws an error:

I do not require any "Prefix" or "Header" in the message and have changed to:

Once you disable prefix mode (why???) then you can no longer assume that messages will arrive as a single "packet". You should expect messages to be split or merged.
